Purpose: A heatmap is a graphical way of displaying a table of numbers by using colors to represent the numerical values. For example, low values might tend towards cool blue tones while higher values tend to hotter orange and red tones. Heatmaps also re-arrange the rows and columns of the table so that similar rows, and similar columns, are grouped together, with their similarity represented by a dendogram (separate dendograms for rows and for columns). This webtool uses the heatmap tool, "heatmap.2" of the gplots package of the statistical environment R: A Language and Environment for Statistical Computing.
For more details see the Heatmap Explanation.
